Suburban

While driving a 2023 Chevrolet Suburban (VIN: 1GNSKFKD2PR392580), my 10-year-old son was seated in the second-row center seat and was properly buckled in with the factory shoulder/lap belt. He turned around briefly to grab something from the back of the vehicle, and during that movement the seatbelt fully extended and then locked in the automatic locking mode. The retractor would not release tension afterward. The belt continued tightening around his torso, and no amount of slack could be pulled back out. The belt became so tight that he was unable to breathe comfortably or free himself, and the locking mechanism would not disengage even after the vehicle was stopped and turned off. The seatbelt remained fully cinched and would not retract or loosen under any circumstances. Because the belt created a serious entrapment hazard and my child could not safely be removed, I was forced to cut the seatbelt to free him. This appears to be a dangerous malfunction of the seatbelt retractor/locking system and presents a significant safety risk, especially for children who may shift or turn in their seats during normal use.

My 2023 Chevrolet Suburban High Country (VIN: [XXX] ) suffered a sudden and dangerous engine failure while my wife was driving 70 mph on the interstate returning from our child’s sled hockey tournament in Ohio. The vehicle gave no warning lights, alerts, or diagnostic messages before the failure. While driving in the right lane, the vehicle began losing power and making a loud noise. My wife exited the highway and contacted OnStar, who told her the tow would take over an hour and only cover three miles to closest dealer, leaving her stranded in an unsafe area. She attempted to carefully reach a nearby dealership. During this attempt, the vehicle completely shut off and she lost all engine power. The vehicle lost all power making the final turn into the dealership coming to rest in the middle of oncoming traffic of a four lane road. The Suburban would not restart. A tow truck arrived and transported the vehicle to a dealership. When they arrived, the tow driver noticed smoke and a strong burning odor coming from the engine compartment and told her to move away from the vehicle because it could potentially catch fire. The vehicle was left in the lot with the hood open and positioned away from the building for safety. The dealership has determined the engine suffered a catastrophic failure and requires complete replacement. Multiple related components may also be affected. This occurred on a vehicle with only 54,000 miles that was purchased three months earlier. This incident created a serious safety risk for my wife, who was nearly stranded on an interstate and had to maneuver a powerless vehicle across several lanes of traffic. I am reporting this to NHTSA due to the sudden failure at highway speed, lack of warning, and potential fire hazard.

I was driving the vehicle and without warning it just stopped shut off and immediately shot an error code that there was a critical issue with the engine and that the oil pressure was low, and the vehicle would not start and was not drivable. It had to be towed to a dealership.

My 2023 Chevrolet Suburban with the 5.3L V8 engine has experienced lifter failure twice within less than [20,000 miles]. Both times the vehicle developed a misfire, engine belt like noise and was diagnosed by the Chevrolet dealership as having collapsed AFM/DFM lifters. All oil changes have been done at the dealership using GM-approved oil. The issue appears to be a known problem on 2021–2023 GM vehicles with the 5.3L L84 engine. GM has a technical service bulletin (PIP5776H) regarding lifter collapse, but no permanent fix has been provided. I am concerned this could lead to engine failure or stalling while driving, creating a safety hazard.

I went to get in my 2023 suburban this morning to travel to the gym. It started but it would not shift out of park. I looked down and noticed the check engine light was on, the ABS light was on, and the park brake light was on with a lock and wrench. I had no issues since I purchased it used in March 2025 and yesterday it was driving fine.

The contact owns a 2023 Chevrolet Suburban. The contact stated that while driving at 10 MPH, there was an abnormal rumbling sound coming from the engine, with the check engine and traction control warning lights illuminated. Due to the failure, the contact restarted the vehicle and drove to an independent mechanic. The mechanic performed a diagnostic test on the vehicle and discovered a misfire in cylinder #3. The mechanic replaced the cylinder #3 ignition coil; however, the failure persisted. The contact then had another independent mechanic at the same shop inspect the vehicle, and the mechanic diagnosed the vehicle with engine failure. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 52,000.

When driving making a left or right hand turn my 2023 Suburban loose power and turns off and it is thrown in N and state to press start to restart my SUV. No codes are given to determine the issue. This has happen a handful of times. It has been taken into Chevy and they are unable to diagnose the problem. During the one visit they stated it was the battery and replace it and it has done it again. This is a very unsafe to drive the SUV as I'm afraid someone will rear end me and hurt me or someone else.
